Sodium and oxygen lewis dot structure

Sodium Oxide having a chemical formula of Na2O, is a metal oxide. It is also known as an alkali metal oxide as it comprises two sodium and one Oxygen atoms. The compound is widely used in ceramics and glasses. Also, this molecule is different from the other organic molecules as it is made up of one Metal Sodium and one non-metal Oxygen. Such compounds are known as ionic compounds, as there are ionic bonds formed in such molecules. Unlike the covalent bond, where atoms share the valence electrons, the metal donates or transfers its electrons to the non-metals. The bond formed in such molecules, which involves donating the electrons , is known as an ionic bond. For determining the Lewis structure of any molecule, one needs to know the valence electrons for that molecule. Here the metal oxide consists of two Sodium atoms and one oxygen atom. As mentioned above, the Lewis structure for this molecule will be different as it is an ionic compound. Unlike the standard process of determining the central atom and arranging the electrons around it, we follow it differently.! If you look closely, Oxygen needs two valence electrons to have a complete octet. And these two electrons will be donated by the two Sodium atoms here. Transfer the one valence electron on Sodium atoms to the Oxygen atom. After transferring electrons, Oxygen has a complete octet, and it also acquires charges as it is accepting electrons.

In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, a simple way of representing those valence electrons would be useful. A Lewis electron dot symbol or electron dot diagram or a Lewis diagram or a Lewis structure is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom. These dots are arranged to the right and left and above and below the symbol, with no more than two dots on a side.

Lewis used dots to represent the valence electrons in his teaching of chemical bonding. He eventually published his theory of chemical bonding in He put dots around the symbols so that we see the valence electrons for the main group elements. Formation of chemical bonds to complete the requirement of eight electrons for the atom becomes a natural tendency. Lewis dot symbols of the first two periods are given here to illustrate this point.
